Perf-a-board roller type tool

ABSTRACT

An elongated roller with an outer cylindrical surface having many sharp points equidistantly spaced extending outward from said surface at right angles thereto. A handle secured to the roller enables the roller to be rolled over a suitable surface to place small indentations therein.

SUMMARY We have discovered that when many closely spaced indentationsare formed in these hard surface regions, the paint applied thereto willexhibit more permanent and lasting adhesion. Moreover, when theseindentations are formed in surfaces to be repainted, the formation ofindentations assists in clearing away loose paint as well' as preparingthe surface regions as previously described.

In our invention we provide elongated roller means with an outercylindrical surface. Many sharp points uniformly spaced over the entiresurface extend outward therefrom at right angles thereto. Manuallyoperable means secured to the roller means enables the roller means tobe rolled over the outer surface of wood,

siding to produce the desired indentations therein.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings:

FIG. l is a partially cut away side elevation of one form of ourinvention;

FIG. 2 is one end elevation of the structure of FIG.

FIG. 3 is an opposite end elevation of the structure of FIG. ll;

FIG. 4 is a detail perspective of a modification of the structure ofFIG. 1;

FIG. 5 is similar to FIG. 1 but showing another modification thereof;and

FIG. 6 is a detail showing part of the structure of FIG. 5.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Referring first to FIGS.1-3, an elongated solid roller 10, cylindrical in shape, has an axialbore 12 with recesses 14 at each end. The outer surface of the rollercarries a plurality of closely and uniformly spaced points 16 extendingoutward from the surface at right angles thereto. Typically the outersurface and points can be of metal and can take the form of a sleeve Aslidably engagable with an inner plastic or wood cylinder 10B.

A shank has an elongated section 18 extending through the bore with afree end exposed in one end recess and held in place by nut 20. Theother end of the section 18 extends outward from the other end of theroller, is bent at right angles as shown at 22, is bent again at rightangles to form an extension 24 parallel to.

section 18 and spaced from the roller and is bent again at right anglesto form a final portion 26 engaged by handle 28. A sleeve 30 may berotatably disposed over extension 24. The invention can then be used aspreviously described.

The depth of points 16 can decrease linearly with increasing separationfrom one end of the roller as shown in FIG. 4. This enables the rollerto be applied to siding tapering in thickness (such as in simulatedshingles) to form indentations of uniform depth despite the differingresistance of the siding, as its thickness varies, to the indentationprocess.

In FIGS. 5 and 6, the roller 10 is replaced by a plurality of like discs32. Each disc has a central opening 34 through which section 18 passesand also has an offset hole 40 and an oppositely disposed offset prong42. The prongs and holes are engaged whereby the discs are lockedtogether side by side and act as a rigid cylinder whereby the same typeof roller use as previously described can be obtained.

While the length of the cylinder can vary, I have found that a length ofless than 7 inches is satisfactory and that a length of 3 inches isexcellent. The points can have the shape of an inverted V, but bestresults are obtained when the points are rounded with the shape of anold phonograph needle or large sewing needle. If desired, the cylindercan be a solid tube with the points machined into the outer surface.

While we have described our invention with particular reference to thedrawings, such is not to be considered as limiting its actual scope.

Having thus described this invention, what is asserted as new is:

1. In combination:

elongated roller means having an outer cylindrical surface and an axialbore;

a plurality of sharp points closely and uniformly distributed over saidsurface and extending outward therefrom at right angles thereto;

a shank having an elongated section extending through the bore with afree end exposed in one end recess and held in place therein;

the other end of said section extending outward from said bore and backin U-shape again to form a portion parallel to the outside of saidroller;

said section being further bent at right angles at the center of theroller for a final portion;

a handle on the end of said final portion to be grasped by one hand; and

a sleeve rotatably disposed over the portion parallel to the roller tobe grasped by the other hand. =0

1. In combination: elongated roller means having an outer cylindricalsurface and an axial bore; a plurality of sharp points closely anduniformly distributed over said surface and extending outward therefromat right angles thereto; a shank having an elongated section extendingthrough the bore with a free end exposed in one end recess and held inplace therein; the other end of said section extending outward from saidbore and back in U-shape again to form a portion parallel to the outsideof said roller; said section being further bent at right angles at thecenter of the roller for a final portion; a handle on the end of saidfinal portion to be grasped by one hand; and a sleeve rotatably disposedover the portion parallel to the roller to be grasped by the other hand.
